Winter. The snow is falling. The wind is blowing.The ground is white. People wear warm clothes: warm hats, warm coats, scarves and mittens, warm socks, trousers, sweaters, warm boots. Spring. The trees are green. The sky is blue. The wind is warm. People take off warm clothes. They wear jackets and jeans, caps and light scarves, light shoes. Summer. The sun is shining, there are bright flowers. The days are hot. Реople put on dresses, T-shirts, shorts, sandals.They wear sun-glasses. Autumn comes. It often rains. The sky is often grey. Cold winds blow. People put on raincoats and gloves. They often wear umbrellas with them. In autumn many people enioy watching beautiful leaves which turn yellow, brown, red and orange. I like all four seasons of the year!
Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman.
He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb.
He was one of the first inventors to apply the principles of mass production and large teamwork to the process of invention, and therefore is often credited with the creation of the first industrial research laboratory.
Edison is the fourth most prolific inventor in history, holding 1,093 US patents in his name, as well as many patents in the United Kingdom, France, and Germany.
He is credited with numerous inventions that contributed to mass communication and, in particular, telecommunications.
These included a stock ticker, a mechanical vote recorder, a battery for an electric car, electrical power, recorded music and motion pictures.
His advanced work in these fields was an outgrowth of his early career as a telegraph operator.
Edison originated the concept and implementation of electric-power generation and distribution to homes, businesses, and factories – a crucial development in the modern industrialized world.
His first power station was on Manhattan Island, New York.
